摘要
十屋断陷为西断东超箕状断陷 ,上覆坳陷地层。断陷地层的暗色泥岩是好的油气源岩 ,最好的储集层是坳陷层的泉头组 (K2 q) ;油气能够运移到泉头组聚集成藏是最有利的成藏组合。构造运动控制盆地的演化、油气的生成、构造圈闭的形成、原生油气藏的破坏及浅部次生油气藏的形成。沉积环境控制源岩、储层的发育特征、油气区域分布层位及原生油气藏的形成。嫩江期末构造运动控制局部构造的油气分布层位及次生油气藏的形成。早期断裂停止活动时期 ,不是油气垂向运移通道 ,但是能形成断鼻、断块圈闭聚集油气而成藏 ;断裂在活动时期才能作为垂向运移通道 ,以致在浅部形成断鼻。
Shiwu fault depression is a dustpan like one with faulted west part,superimposed east part and overlied depression formation.The best source rock is the dark mudstone in the fault depression interval and the best reservoir is the Quantou formation in the depression interval.The best favorable reservoir forming assemblage is that oil and gas can migrate into Quantou formation and accumulate and form reservoir.The basin evolution,the hydrocarbon generation,the structural trap formation,the destruction of th...
